Origins & rise
The Kingdom of Saudi Arabia is the third and most durable state built by the Al Saud dynasty of central Arabia. The family's political project began in 1727–1744, when Muhammad ibn Saud, ruler of the oasis town of Diriyah near Riyadh, allied with the religious reformer Muhammad ibn Abd al-Wahhab, founder of the austere revivalist movement known as Wahhabism. That alliance of sword and creed powered the First Saudi State (destroyed by Ottoman-Egyptian forces in 1818) and the Second Saudi State in Najd (which fell to the rival Rashidis of Ha'il in 1891, driving the Al Saud into exile in Kuwait). In 1902 the young Abdulaziz ibn Abdul Rahman Al Saud — "Ibn Saud" — recaptured Riyadh in a celebrated night raid, beginning three decades of conquest: the Rashidi heartland of northern Arabia by 1921, the oil-rich al-Hasa coast from the Ottomans in 1913, Asir in 1920, and finally the Hashemite Kingdom of the Hejaz in 1924–1925, after Britain withdrew its support from Sharif Hussein. On 23 September 1932 the dual "Kingdom of Hejaz and Nejd" was formally renamed the Kingdom of Saudi Arabia.
History & key rulers
Abdulaziz ruled until his death in 1953, consolidating the new state with the fanatical Ikhwan tribal army — later suppressed at the Battle of Sabilla (1929) when it threatened British-protected neighbors — and fixing borders by treaties in the 1920s–1930s, including the 1934 Treaty of Ta'if with Yemen. Oil was discovered at Dammam No. 7 in March 1938, and in February 1945 Abdulaziz met President Franklin D. Roosevelt aboard USS Quincy, founding the enduring Saudi–American bargain of oil for security. Six of Abdulaziz's sons have reigned in turn: Saud (1953–1964, deposed amid family rivalry and fiscal chaos); Faisal (1964–1975, modernization and the 1973 oil embargo, assassinated by a nephew); Khalid (1975–1982, whose reign faced the 1979 Grand Mosque seizure and the Iranian Revolution); Fahd (1982–2005, the 1991 Gulf War and rising Islamist militancy); Abdullah (2005–2015, cautious reform); and Salman (2015–present), whose son Crown Prince Mohammed bin Salman is the de facto ruler, pursuing the Vision 2030 diversification program, the intervention in Yemen, and selective social liberalization alongside tight political control.
Government, religion & culture
Saudi Arabia is an absolute monarchy governed along Islamic lines: the king combines head of state and government, the Quran and Sunna serve as the constitution, and Wahhabi (Salafi) doctrine shapes law and public life. The kingdom styles itself "Land of the Two Holy Mosques," custodian of Mecca and Medina, and the annual hajj gives it unique religious authority across the Muslim world. Oil transformed a poor desert society into a rentier welfare state; it holds among the world's largest proven petroleum reserves and is the leading oil exporter.
Peak & territory
At roughly 1.9 million km² the kingdom occupies about 80 percent of the Arabian Peninsula — Hejaz, Najd, al-Hasa and Asir — bounded by Jordan, Iraq and Kuwait to the north, the Gulf states to the east, and Yemen and Oman to the south. Its boundaries were essentially complete by 1934 and have changed little since.
Present status
The kingdom remains extant and regionally dominant, balancing oil rents, religious legitimacy, and the American security relationship while attempting to diversify its economy and manage rivalry with Iran.
